Question

Energy Efficiency =

Useful Energy Output/Total Energy Input x
100 (%)
If a power plant uses 100 units of energy to
create electricity and the output is 35 units,
what is the energy efficiency of the power
plant?
A. 100%
B. 45%
C. 35%

Answer 1

Answer:
the energy efficiency of the power plant is 35%, which is option C.

Step-by-step explanation:

The energy efficiency of the power plant can be calculated using the formula:

Useful Energy Output / Total Energy Input x 100%

In this case, the useful energy output is 35 units, and the total energy input is 100 units. Therefore, the energy efficiency is:

35 / 100 x 100% = 35%

Therefore, the energy efficiency of the power plant is 35%, which is option C.
